In the map of period-doubling bifurcation, stable fixed points bifurcate to $2^n$ fixed points, and in the chaotic region, the chaotic bands merge to 1/$2^n$ bands. In a typical map, the chaotic bands expand to a broad chaotic band during the merging process, so called crisis. In this paper, interior crises appearing during the merging process will be discussed by using our map and will be analyzed the characteristics of the phenomenon by obtaining the Lyapunov Exponents.

The purpose of this study was to suggest the spatial structure among residential behaviors in relation to work space. To find the structure, Multi-Dimensional Scaling analysis was used. Respondents were 349 middle income housewives living in apartments in the area of Caopital region. Data were collected through the questinnaire survey. For the future residential interior design, following points were sugtested. A laundary space neess to be developed independently , being separated from both bathroom and kitchen/dining space. A new area which will give housewives some territoriality and also function as home office needs to be considered. A space configuration which satisfies the organic relationships among laundary behaviors such as washing dying, ironing and folding , needs to be systematically planned, with two adjoining separate zones of wet and dry utility . The present bathroom nees to be more incorporated to the private bedroom rather than to workspace.

Nowdays there needs a lot of nursery facilities for the women those who work. Whit the government promotion policy the quantity of those are progressive. The aim of this study is to upgrade the quality of the nursery with suggesting the architectural interior design criteriors. The criteriors are based on three important points that are children's emotion, body scale and especially their safety. Color, furniture style and qtmosphere are concern-ing about the first. The size of the furniture, urinal and window height etc. are abduy the second. Stair, handrail interval etc. are about the last. I hope that these criteriors will help those who want to design nursery and those children who use the build-ings.

Recently as urban buildings become higher and deeper by reason of economic growth and concentration of population into cities, the supporting technology becomes largely advanced and many buildings have been constructed making use of new materials and structure methods. As these large buildings accomodate large population and its insides are variously used for uses, disasters in buildings have been growing day by day. One of the main reasons of the disasters are the varity of building functions. Among the disasters, the damages by fire accidents become very serious as losses of lives and property become increasing. Here, although there shoule be many other ways to minimize these disasters, 1 would review choice of interior materials of buildings and improvement of blind points and week points in construction methods for the purpose.

Much evidence points to the fact that Korean traditional architecture has long reflected traditional Korean philosophy. If what this evidence points to Is true, there is much more insight to be gained about this connection. It is important to begin with the idea that Korean culture stemmed from Confucianism, Buddhism, and Taoism. All three share similar ideas, and this study will set out to prove that topology, an anti-Euclidean school of thought created at the end of the 19th century, shares many of the same core ideas as the three mentioned above. Transitively, if Korean traditional culture is reflected in Korean traditional architecture, and topology shares many of the same core ideas, it seems that topology should be accepted into the mainstream of architectural design. This study will aim to interpret space structure forms and space constructions of the Korean traditional architecture from the topological perspective.

The purpose of this research is to suggest the ultimate solution to the interior elements and ways to express specific function within interior design of the new high-speed train station in Korea through careful studies based on the characteristics of each areas in the stations. During the research, it became very clear that the most important points in designing of the high speed train station's interior space can be found from close examination on whether each space allocation was thoughtfully organized to provide enough space to accommodate various activities of the users. Another point is to realize, within the space program, that there should be a clear understanding of the future expansion plan and reserving sufficient areas for the future growth. Also the problem of requiring larger floor areas to accommodate various functions divided by separate units must be recognized simultaneously during the programming. The new high-sped train must be able to function as a multi service facility of the future. In summary this research is to present datas and suggestion to various areas in the station and redefine its new meaning of train station space program with much borader concept which can be adopted to the process of better space programing.

This stduy aimed to suggest a possible way for a new setting of interior design education through analyzing educational situations of domestic interior design societies. The study showed that interior design education should not follow expressive methods made from practical work which had been popular in the past and it should establish fundamental formation to make interior design education useful in industrial fields through active educationalindustrial complex. Interior design education is not possible without interrelationship with other professional fields and cooperative attitudes among them. The rapid development in the modern industrial world and the ever-growing information processing world regardless of ideology and regiional boundaries indicate that the future of interior design education will be no longer effective with traditional education systems. The idea suggested in this study may be understood as a bridge between the educational reality and its ideal in interior design teaching. The main points of the study are follows. First, the projects of advanced interior design should be focused on increasing the ability for problem solving rather than accumulating basic knowledge. Second, motivation is important for the maximization of the efficiency of educatiov. Therefore a few suggestions in establishing design conditions, as strategies of inducing 'attention', 'self-confidence', 'satisfaction', and 'relevance' are closely examined to propose practical application methods. Third, educational methods should be developed towards creativity in order to increase abilities of thinking and expressiov. Finally, it is necessary to explore various device which help internship participants to get experiences with a sense of practical situations in industrial fields. This could be possibly done by enforcing academic grades for the work done as an internship participation; by employing workmen in industrial fields as faculty members; and by bringing faculty members into actual industrial situations and providing workmen with lectures. A new approach for a better design education seems to be desirable for the future.

We introduced the concepts of the generalized accumulation points and the generalized density of a subset of the Euclidean space in [1] and [2]. Using those concepts, we introduce the concepts of the generalized closure, the generalized interior, the generalized exterior and the generalized boundary of a subset and investigate some properties of these sets. The generalized boundary of a subset is closely related to the classical boundary. Finally, we also introduce and study a concept of the thickness of a subset.

The purpose of this study is to analyze the phenomenological approaches in Holl's architecture centered on his Nelson-Atkins Art Museum. This study mainly deals with concrete and practical architectural contents based on his recent works rather than existing studies about philosophical point of views to his architecture. Because Holl has had turning point from theoretical research to practical application and development stage. Therefore, this study aims to find out Holl's phenomenological approaches that were different from his early works. Nelson-Atkins art museum shows effect of luminosity as well as inflow of light in the phenomenological experiences of light and space. Holl gave new addition building that he designed contrasts of massing, transparency of material, colors to enhance existence of new building through phenomenological experiences. Narrow and long circulation and various focal points provide multi-view points and overlapped spaces in body experiences As a result, Holl shows shifts from theoretical application to architectural utilization. Nelson-Atkins art museum is important in that this project is one of stating points about this shift.
